Genuine Brother® Accessory. 3 pieces included. This white, paper fiber iron-on stabilizer provides a stable surface for machine embroidery, keeping fabric from stretching and distorting while it is in the hoop. This stabilizer is useful for projects that require a temporary stabilizer. Use a warm dry iron to attach to the wrong side (back) of your fabric. When finished with embroidery, gently tear-away remaining stabilizer. Test first for complete removal on delicate fabrics.
